The Schrodinger's cat thought experiment was an attempt by Schrodinger to show that cat cannot be alive and dead when it was not looked at. The thought experiment was appreciated by Einstein and Einstein said he appreciated Schrodinger for putting forth the experiment. This is where quantum and classical (the world we see around) physics mismatch. Some would say that the Geiger counter that measures the decay of the chemical collapsed the wave function.
People that do not agree with the experiment would say that the Geiger counter collapsed the wave function because it measured/observed the decay that released the gas. I agree with this view. In my understanding, any measurement, observation, and calculation collapses the wave function and the cat takes a stand (alive or dead)
Einstein put another experiment saying that if you looked at the moon, the moon is there and you see it, and if you turn around, you are still pretty sure that the moon is still there behind you. These experiments are just a different way of looking at quantum mechanics and how it contradicts classical mechanics. These experiments base on whether if you agree wave function collapse occurs or not, whether there is fundamental contradiction between quantum and classical mechanics, you think whether wave-particle duality is real, how you interpret this duality if wave particle duality exists, if you think the Geiger counter collapsed the wave function or no wave function collapse occurred.
I honestly don't know how to answer Schrodinger cat thought experiment, but if I have to answer in some form, the wave function was already collapsed and if we weren't looking at the cat the cat is alive or dead and there is no contradiction between quantum and classical mechanics in this case. The Geiger counter collapsed the wave function because it was observing/measuring the chemical and the decay will "take a stand," and it will decay or not and depending on that the cat will be alive or dead.
